02 sensors

The sensor before the catalytic converter isn't an issue I don't think, but the one after is going to trigger my SES light when I remove my catalytic converter. How would I go about fixing that issue to get the light to go off?

How much are the simulators? And how would I go about tuning the sensor out? Maybe that's a stupid question but I'm not all that familiar with tuning.

About $100 for sims. You could have a mail order tune done where you ship your PCM away and they recalibrate and send it back. And you could repin the O2 wires at the PCM to use your rear harness for front sensors if going with headers, as shown here:https://ls1tech.com/forums/generation-iii-external-engine/1425078-lt-header-guys-no-more-extensions-corvette-o2s.html
